The ISL70005SEHDEMO1Z demonstration board is designed to demonstrate the performance of the ISL70005SEH radiation hardened, 3A buck regulator and 1A source/sink LDO. The same board can be used to demonstrate the ISL73005SEH part, which is the same silicon die offered with different radiation assurance screening. The demo board is specifically configured for the DDR memory VDDQ and VTT supply rail applications. The buck regulator output voltage is pin jumper selectable for 2.5V, 1.8V and 1.5V. The LDO output voltage is configured to track half of the buck regulator output voltage. The ISL70005SEHDEMO1Z only requires one input supply voltage at the PVIN terminal for operation. The PVIN accepts an input voltage range of 3V to 5.5V.
